SOURCE: Buick LeSabre left front window will not close

Don it. Good half day for amateur. Get Chilton 86-99 Bonneville, 88, Lesabre manuel.. Tricky to find bolts are under end flaps on door close handgrips. Took me a day to figure that one out. Others under light at lip of back of door. Book indicates to strart with window 3/4 up if you can. Flip up window control at rear of panel. After all screws are out raise outer edge of armrest and look for notches 4" and 11-1/2" from rear of armrest to slide inward to remove. There are screws under the door handle too. Screws everwhere. When pulling bottom of panel from door lift with a notched bar to avoid tearing the fasteners out of the cardboard panel. Two screws behind seatbelt notch at top need to come out to allow positioning the glass. The panel at the bottom of the top opening can be removed for more fredom in positioning the glass when reinserting the ball in the lower track on the window. Tape glass with duct tape to keep it from falling. Drill the factory rivets that hold the old regulator and I replaced with stove bolts with nylon locknuts slotted head to the inside the car. Can't remember the size, probably 1/4 or 3/16". Remove speaker if in front bottom of door to use your hand to do work in the door. You must twist the regulator forward with window 1/2 down to remove the ball from the socket in the bottom sliding metal track at the bottom of the window. Don't drop the window after removing the socket, tape it in place. Don't know what you do if you cannot move it to 1/2 up position. By the way, the body shops say you must use rivets, not screws or it will shift, but I have had no problems with the screws for reinstallation several years old. The rivet they use take a big hydraulic pop rivet gun that you won't have. Good luck, I don't envy you. Need to do other window on my 91. The window control may not be the same on the Custom, mine is the Ltd. you may be able to remove the motor from the regulator in the door without removing the regulator if you can figure out how to get the bolts that hold the moter to the regulator. inside the door.

SOURCE: 2000 BUICK LESABRE BLOWER MOTOR

The blower motor should be two wires. Backprobe and find out which is power and which is ground and bench test it. You could have a bad blower but it sounds more like a defective speed resister.

SOURCE: '91 Buick LeSabre heater blower motor

Are you sure the blower motor is defective? If the blower motor resistor pack is bad the blower will not work. Have you applied 12 volts directly to the blower motor to verify it is bad? I have not replaced a blower motor on your particular car but it is usually a labor intensive repair. Depending on where you have it repaired the cost could be as little as $150 and up. Hard to say without actually doing it. Replacing the Resistor Pack is a fairly easy repair, so hopefully that is your problem.

I believe that i have a blown heater motor fuse on a 1991 buick lesabre. which fuse is it and where is it located?


Check the power at the connector to the blower motor with a test light or gauge. Mine would blow at times and I turned it on unplugged connector and reconnected . It works fine after I cleaned and fixed it.
